Israel's nature authority said Tuesday that a vulture from one of its reserves had been captured on suspicion of espionage in neighbouring Lebanon after flying across the border.

Members of the Israeli public phoned the Israel Nature and Parks Authority to alert it to Facebook reports and pictures of a vulture with an Israeli identification ring and location transmitter captured by residents of the south Lebanese town of Bint Jbeil, spokeswoman Tali Tenenbaum told AFP.

"Reports passed to us show the vulture tied with a rope by local people who write that they suspect Israeli espionage apparently because of the transmitter attached to him," a statement by the authority said.
